UNITED STATES PATENT GEEIGE.

MARTIN RISLEY, OF SPRINGFIELD, MASSACHUSETTS.

IMPROVEMENT IN EYEGLASSES.

Specification forming part of Letters Patent No. 142,277, dated August 26, 1873; application led May 19,1873.

To all whom it may concern:

Be it known that I, MARTIN RIsLEY, of Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Eye-Glasses, of which tlie following is a full, clear, and exact description, reference being had to the Iannexed drawing forming a part of the same, and in which the figure illustrates a view in side elevation of a pair of eye-glasses embodying my improvement.

The nature of this invention consists in oonstructing the eye-glass frames with springs or loops having clips or flanges to receive, and by means of which the nose-band is secured thereon, substantial] y as hereinafter more fully set forth.

To enable others to make and use myinven'- tion, I will proceed to describe it.

In the drawing, thefrarnes of the eyeglasses, which are designated by the letters A A,V are constructed with loops or enlargements A A made of some elastic metal, and so disposed thereon as to impinge against the nose when the glasses are adjusted to the face of the wearer, and thus serve as the nose-springs. In addition to this function, they, the loops or springs Al A', by reason of their elasticity, enable the frames of the glasses to be expanded and contracted, by which the latter can be displaced and replaced whenever occasion may require, thus dispensing with the trouble and expense heretofore experienced in forming the frames in two or more parts fastened together by flanges, screws, &c., for that purpose. B refers to the ordinary noseclasp, which is adjusted to the nose springs or loops A A by means of flanges b b formed upon or embracing the latter and overlapping the ends of the former, thus forming clips or the loops Al A', having the flanges or clips b b to secure the nose-band by swaging the same thereon, substantially as shown and described. In testimony whereof I have hereunto signed ,my name this 16th` day of May,'1873, in presence of two subscribing witnesses.
